Review on 🔌 SoundBox 4-Gauge OFC AWG Amp Install Kit: Complete Oxygen-Free Copper Amplifier Wiring by Kevin Garcia

I ordered a 4 gauge wire harness in January 2020. It is now August 2020 and it is not working. The woman told me her sub stopped working. So I started testing everything. I got to the 12v power wire and pulled the fuse out thinking it was my problem. The fuse is well checked. The wire was stiff from the fuse to 6 inches towards the battery. I cut it open and found everything was rusty and broken into pieces. When I installed this I used whatever came with it so everything should be fine. It looks like the wire and end of the fuse didn't get along which is causing the corrosion. Also, I live in Virginia so the salt didn't corrode.
